For twenty-five years, one number haunted the Bighorn 100 Trail Run — 18 hours.
No runner had ever cracked it.
Then Bo Shelby showed up in Dayton, Wyoming, and changed everything.
In a performance that will be talked about for years to come, Shelby didn’t just break the course record — he shattered a psychological barrier that a quarter century of elite runners couldn’t touch.

The Run That Rewrote History
Shelby crossed the finish line at the Bighorn Trail Run in 17 hours, 58 minutes, and 3 seconds — becoming the first person in the race’s 25-year history to finish in under 18 hours.
That’s not a record. That’s a redefinition of what’s possible on one of ultrarunning’s most punishing courses.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
The Bighorn 100 is not a forgiving race. It winds through the rugged Bighorn Mountains, covering 100 brutal miles of climbing and descending terrain with a 35-hour cutoff — a course where most competitors arrive simply hoping to earn a finisher’s buckle.
Shelby arrived to rewrite the record books.
A Podium That Belongs in the History Books
What made Friday’s race even more extraordinary was the depth of competition behind him.
Ben Quatromoni crossed the line in second place with a time of 18:10:31 — a finish that would have stood as a course record on any other day in the race’s history. It now sits as the second-fastest Bighorn 100 ever run.
Let that sink in. The second-place finisher also broke the previous all-time record, and his name won’t even be listed at the top.
John Dragon rounded out the podium, finishing third in 19:48:48 — a performance that, on most race days, would have been the story of the weekend.

This wasn’t just a fast race. It was arguably the deepest, fastest men’s field performance in Bighorn 100 history.
Handelman Dominates the Women’s Race
On the women’s side, Leah Handelman took the top spot with a winning time of 24:23:35.
Covering 100 mountainous miles through the Bighorns is a feat unto itself. Doing it as the day’s women’s champion makes Handelman’s name one to remember heading into the back half of the ultrarunning season.
Why This Moment Matters Beyond the Stopwatch
Why This Moment Matters Beyond the Stopwatch
In ultrarunning, certain numbers take on a life of their own.
The sub-18-hour barrier at Bighorn had become one of them — an invisible wall that years of talented, determined athletes couldn’t breach. Until Friday.
Shelby’s finish doesn’t just move a number on a leaderboard. It fundamentally shifts the conversation about what elite performance looks like on this course, and it guarantees that future competitors will arrive with a new target burned into their minds.

Twenty-five years of Bighorn history. One Friday afternoon in Wyoming. A new ceiling — and for the first time, proof that it can be broken.
